Rochelle Steffen had her dogs, Monte and Roxie, chew up 22 Vick cards, she listed the remnants on eBay, and then she sold them for the whopping amount of $7,400.

On the auction, Steffen said she would donate all of the proceeds to the animal shelter of the winning bidder’s choice. This caused a bidding frenzy among 31 different bidders to win the auction.

This dog chewed up Vick cards were the most expensive Vick item on eBay, with mint cards, autographed jerseys, and other collectibles selling for far less.

The success of this auction has resulted in more than 25 other listings this week that are selling dog chewed up and torn Vick cards or memorabilia.

“When I started this I only expected to get $100 for a local shelter,” Steffen said. “But it’s received so much attention. It’s for such a good cause that jumps every boundary.”

She added that she has been overwhelmed with positive responses, and many people said her auction inspired them to donate money to animal shelters.

The Humane Society of the United States has seen a large spike in donations since Vick was indicted on federal dogfighting charges last month, said Ann Chynoweth, director of the society’s Animal Cruelty and Fighting Campaign.

Vick’s collectibles were once considered as some of the most sought after memorabilia. But now, the values of his cards, jerseys, autographs and other items have drastically decreased. His 2001 rookie card was once valued at more than $1,000, but now it is being traded at $285 to $400.
